Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621942, here are decompositions:

19 + 33621923 = 33621942
31 + 33621911 = 33621942
41 + 33621901 = 33621942
61 + 33621881 = 33621942
83 + 33621859 = 33621942
103 + 33621839 = 33621942
181 + 33621761 = 33621942
191 + 33621751 = 33621942

Showing the first eight; more decompositions exist.
